IMPROVEMENT IN MACHINES FOR MAKING BOOT AND SHOE SHANKS.

s cification forming an of Letters Patent No. 19 ,525, dated December25, 1877 application filed November '20, 1877.

To all whom it may-concern: l

Be it known that I, J EREMLAH M. WATSON, of Sharon, of the county ofNorfolk and State of Massachusetts, have invented a new and usefulMachine for Manufacturing Boot or- Shoe Shanks; and do hereby declarethe same to be described in the following specification and representedin the accompanyin g drawings, of which- Figure 1 is a top view, Fig. 2an end elevation, Fig. 3 a longitudinal section, and Fig. 4 a transversesection, of it, the plane of section of Fig. 3 being through the knivesfor effecting the chamfering of the blank lengthwise. Fig. 5 is a topview, Fig. 6 an edge elevation, Fig. 7 a longitudinal section, and Fig.8 a transverse section, of a shoe-shank as made by such machine.

In the drawings, A denotes the frame of the machine as provided with adriving-shaft, B, carrying near one end a cutter-wheel, O. This wheelhas in it a circular arcal slot, at. It also has affixed to its face orside two cutters, b c, for producing the end or transverse chamfering ofthe shank. It also has on its face one or more cutters, d, for splittingthe shank partially lengthwise. Furthermore, such wheel has on its facea cutter, e, for separating a shank fiom a block. It also has, or mayhave, for such cutters suitable throats for discharge of the block andany shavings resulting from forming the end chamfers.

' In rear of the cutter-wheel 0 there are two cutter carriers or stocks,D E, provided with knives or cutters f g, for producing the lengthwisechamfers 0f the shank. These cuttercarriers, arranged as shown, slidelengthwise when in operation, and during the movement ing revolved, thelevers will be alternately moved, so as to effect, at proper times, the

necessary movements of the'stocks D E of the chamfering-knivesf g.

By a connectingrod, l, the lever G is conjoined with an arm, m,extending from a rockshaft, n, arranged as shown, From the said shaftanother arm, 0, projects alongside of the cam I, which has extended fromit a stud or pin, 10. A spring, q, fixed to the frame A, bears upon thearm 0, and forces it toward the hub 1" of the cam.

During each revolution of the cam the stud will be carried against thearm 0, and will raise it, so as to cause the lever G to be moved upwardofi the block, the spring on the stud passing the arm serving indirectlyto cause the lever G to be forced down upon the block, and to hold itstill, while a shank may be in the act of being formed. While the leverG is raised off the block the latter is to be advanced up to the face ofthe wheel.

As the wheel may revolve, the bevelingcutters f y will be brought intoaction, and will effect the lengthwise chamfer r r of the block. Next,the block near its ends will be chamfered, in order to form the shankwith the end bevels m a. (See Figs. 5, 6, and 7.) This having been done,the splitting-cutter next passes through the block, in order to producethe slit 0 of the shank, which usually extends in such shank in manneras shown in Figs. 6 and 7. Finally, the severing-cutter 0 will separatethe blank from the block, after which the lever G will rise to allow theblock to be advanced.

I do not claim for making shoe-shanks the combination of one or moreslitting-cutters and a severing-cutter with a rotary wheel or disk, andwith a guide or support for a blank to be slit and severed by suchcutters, all being as represented in the United States Patent No.145,024, dated February 25, 1873.

In carrying out my invention I have combined with such devices mechanismfor beveling or chamfering the block, in order that when a shank issevered from it such shank may have the lengthwise or widthwise, or bothlengthwise and widthwise, chamfers, as shown in the drawings. I havealso combined therewith mechanism for firmly holding the block upon itssupporting-bed while such block may be in the act of being cut, all ofwhich I have hereinbefore described.

What, therefore, I claim as my invention is as follows:

1. In combination with the rotary disk 0 and its severing-cutter e, thecutters b c, for producing the end or transverse chamfer of the shank.

2. In combination with the rotary disk 0 and its slitting and severingcutters d e, the cutters b c, for producing the end chamfers or bevelsof the shank, as described.

3. In combination with the rotary disk 0 and its severing-cutter e, thecutters f g, for producing the side chamfers or bevels of the shank,such cutters f 9 being arranged, and provided with mechanism foroperating them, substantially as described.

4. In combination with the rotary disk 0 and its severing-cutter e, thecutters b cfg, for producing the end and side bevels or chamfers of theshank, such cutters f 9 being arranged, and provided with mechanism foroperating them, substantially as set forth.

5. In combination with the rotary disk G and its slitting and severingcutters d e, the cutters b c f g, for producing the end. and side bevelsof the shank, such cutters f gbeing arranged, and provided withmechanism for operating them, substantially as explained.

6. In combination with the rotary disk and its cutter or mechanism, forslitting and severing the block, or for slitting, chamfering, andsevering it, mechanism for supporting and holding the block, consistingof the bed h, the lever G, rod 1, arm m, shaft n, arm 0, gaml-lpin p,and spring q, all operating as set ort JEREMIAH M. WATSON.
